  • Mérigot, Quentin (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    In this paper, we propose an improvement of an algorithm of Aurenhammer, Hoffmann and Aronov to find a least square matching between a probability density and finite set of sites with mass constraints, in the Euclidean ...
  • Martinez, Jonas; Vigo, Marc; Pla-Garcia, Nuria (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Skeletons are powerful geometric abstractions that provide useful representations for a number of geometric operations. The straight skeleton has a lower combinatorial complexity compared with the medial axis. Moreover, ...
  • Goes, Fernando de; Cohen-Steiner, David; Alliez, Pierre; Desbrun, Mathieu (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We propose a robust 2D shape reconstruction and simplification algorithm which takes as input a defect-laden point set with noise and outliers. We introduce an optimal-transport driven approach where the input point set, ...
  • Tagliasacchi, Andrea; Olson, Matt; Zhang, Hao; Hamarneh, Ghassan; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Objects with many concavities are difficult to acquire using laser scanners. The highly concave areas are hard to access by a scanner due to occlusions by other components of the object. The resulting point scan typically ...
  • Kreveld, Marc van; Lankveld, Thijs van; Veltkamp, Remco C. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Detailed geometric models of the real world are in increasing demand. LiDAR data is appropriate to reconstruct urban models. In urban scenes, the individual surfaces can be reconstructed and connected to form the scene ...
  • Solomon, Justin; Ben-Chen, Mirela; Butscher, Adrian; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Cartoon animation, image warping, and several other tasks in two-dimensional computer graphics reduce to the formulation of a reasonable model for planar deformation. A deformation is a map from a given shape to a new one, ...
  • Hildebrandt, Klaus; Polthier, Konrad (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Discrete Laplace Beltrami operators on polyhedral surfaces play an important role for various applications in geometry processing and related areas like physical simulation or computer graphics. While discretizations of ...
  • Weber, Ofir; Ben-Chen, Mirela; Gotsman, Craig; Hormann, Kai (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Barycentric coordinates are very popular for interpolating data values on polyhedral domains. It has been recently shown that expressing them as complex functions has various advantages when interpolating two-dimensional ...
  • Rustamov, Raif M. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    This paper introduces a general principle for constructing multiscale kernels on surface meshes, and presents a construction of the multiscale pre-biharmonic and multiscale biharmonic kernels. Our construction is based on ...
  • Ovsjanikov, Maks; Huang, Qi-Xing; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Despite the large amount of work devoted in recent years to the problem of non-rigid shape matching, practical methods that can successfully be used for arbitrary pairs of shapes remain elusive. In this paper, we study the ...
  • Windheuser, Thomas; Schlickewei, Ulrich; Schmidt, Frank R.; Cremers, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We study an algorithmic framework for computing an elastic orientation-preserving matching of non-rigid 3D shapes. We outline an Integer Linear Programming formulation whose relaxed version can be minimized globally in ...
  • Nguyen, Andy; Ben-Chen, Mirela; Welnicka, Katarzyna; Ye, Yinyu; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Finding an informative, structure-preserving map between two shapes has been a long-standing problem in geometry processing, involving a variety of solution approaches and applications. However, in many cases, we are given ...
  • Papazov, Chavdar; Burschka, Darius (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    In this paper, a new method for deformable 3D shape registration is proposed. The algorithm computes shape transitions based on local similarity transforms which allows to model not only as-rigid-as-possible deformations ...
  • Sahillioglu, Yusuf; Yemez, Yucel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We present a dense correspondence method for isometric shapes, which is accurate yet computationally efficient. We minimize the isometric distortion directly in the 3D Euclidean space, i.e., in the domain where isometry ...
  • Fan, Wenshan; Wang, Bin; Paul, Jean-Claude; Sun, Jiaguang (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We present a novel hierarchical grid based method for fast collision detection (CD) for deformable models on GPU architecture. A two-level grid is employed to accommodate the non-uniform distribution of practical scene ...
  • Vá a, L.; Petrík, O. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Development of geometry data compression techniques in the past years has been limited by the lack of a metric with proven correlation with human perception of mesh distortion. Many algorithms have been proposed, but usually ...
  • Lavoué, Guillaume (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Many processing operations are nowadays applied on 3D meshes like compression, watermarking, remeshing and so forth; these processes are mostly driven and/or evaluated using simple distortion measures like the Hausdorff ...
  • Gregson, James; Sheffer, Alla; Zhang, Eugene (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    While hexahedral mesh elements are preferred by a variety of simulation techniques, constructing quality all-hex meshes of general shapes remains a challenge. An attractive hex-meshing approach, often referred to as ...
  • Dey, Tamal K.; Slatton, Andrew G. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Delaunay refinement, recognized as a versatile tool for meshing a variety of geometries, has the deficiency that it does not scale well with increasing mesh size. The bottleneck can be traced down to the memory usage of ...
  • Nieser, Matthias; Reitebuch, Ulrich; Polthier, Konrad (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Despite the success of quad-based 2D surface parameterization methods, effective parameterization algorithms for 3D volumes with cubes, i.e. hexahedral elements, are still missing. CUBECOVER is a first approach for generating ...
